RCE SD Card replacement

Copy new SD card image.

Use hps_dpm.bin for DPM and DTM hps_dtm.bin

dd if=hps_dpm.bin of=/dev/disk2 bs=1000000

There should be multiple partitions available for mounting.

RTEMS
RTEMSAPP
LINUX
SCRATCH
BOOT

Mount the first "boot" partition. E.g.:

mount /dev/disk2s1 /mnt/sdcard

After it's content of first partition on sd card image:

boot.bin
fpga.bit
readme.bot
uboot.env
uboot_linux.env
uboot_ramdisk.env
uboot_rce.env (?)
version.txt

To set the archLinux environment for a given dpm/dtm host overwrite two boot environment files. To create a boot card for e.g. dpm11:

cp dpm11.env /mnt/sdcard/uboot.env 
cp dpm11.env /mnt/sdcard/uboot_linux.env

Figure out which RCE the newly created SD card correspond to: see COB Layout.

COB Startup Checks

COB status:

When COB is inserted the blue light on the front panel should go away. May need to pull the side levers towards the middle so that they latch.
Identify RCEs from the front panel by noting the cycling patterns that are printed.
We are looking for “not ready”, e.g. "dpmp1-rce2 - not ready".

RTM status:

When being inserted, there is a blue light intermittently when plugging it in.
The RTM board when inserted, a green light should show up when it’s properly inserted.

General:

Check that links are up.
Check that host is pingable and ssh access is possible (JLab computing center might have block on host key changes).
Setup boot and networking scripts.

/usr/clas12/release/1.3.0/slac_svt/svtdaq/daq/rceScripts/setup_linux.sh 'hostname'

NOTE: The first time you setup, the host name might still be e.g. shelf/2/1/1 or similar. You need to active the systemd script. As user "clasrun":

$ssh root@'hostname'
$systemctl enable rce_start
